Donald Trump Jr. probably thought that doing an interview with Pennsylvania news station WTAE would be a cakewalk — but he was very mistaken.

Via BuzzFeed, WTAE — a.k.a., Pittsburgh’s Action News 4 News — cornered Trump Jr. about a Washington Post report that documented how Donald Trump used donations made by other people to his charity foundation to buy a six-foot-tall picture of himself.

The interviewer noted that Trump Jr. is listed as the official director of the Trump Foundation, and he asked if he signed off on the foundation using $20,000 of other donors’ money to buy his father a portrait of himself.

“No, I don’t know anything about that,” responded the younger Trump.

“So it happened and you didn’t know?” the interviewer asked.

“I’m not involved in it,” he replied.

At this point, you can hear an aide in the background asking Trump Jr. to cut off the interview and move on.

“Alright, that’s it,” the aide said. “We have to move on to the next one.”

The interview with WTAE was also notable because Trump Jr. also said that the real reason that his father won’t release his tax returns is that they would be politically damaging to his campaign.

“What we don’t want to do is create a story where then every want-to-be-auditor in the country is going through and saying ‘what if? What if?'” he said. “There’s nothing there.”
